Watch 3-D Movies in 2-D With an Extra Pair of Glasses

3-D is becoming more and more popular, and after a long time, I usually get kind of dizzy. So what I do when I go to the theaters is I use the regular 3-D glasses, and then also carry around my own pair of "2-D glasses"

To make my 2-D glasses, I just basically got 2 pairs of 3-D glasses, and switched the left lens on one with the right lens on the other. Then, I end up with 2 pairs of 2-D glasses.

If you're curious for how this works is that the lens on the left filters out the left picture. The lens on the right filters out the right picture. So when I put both of the left lenses together, I end up with just seeing the left picture. On my other pair of 2D glasses, I end up seeing just the right picture.

This allows me to watch a 3D movie in 2D when I get dizzy from too much 3D. So far, wearing these 2D glasses haven't been giving me headaches.

On this keyboard, pull the spacebar off by pulling up and back from its top edge. I used both hands to minimize torque. It's clipped to key scissors on both ends and in the middle. Refer to the image for the explanation of my fix.

All keyboards are a little different, so your mileage may vary, but it did wonders for mine.
